Abstract

This invention relates to a process for the preparation of quinacridone pigments by (a) heating a reaction mixture comprising (i) a 2,5-dianilinoterephthalic acid, a 2,5-dianilino-6,13-dihydroterephthalic acid, or la 2,5-dianilino-3,6-dioxo-1,4-cyclohexadiene-1,4-docarboxylic acid; (ii) about 0.1 to about 15 percent by weight, based on component (a)(i), of one or more sulfonyl-containing derivatives of 2,5-dianilinoterephthalic acid, 2,5-dianilino-6,13-dihydroterephthalic acid, and/or 2,5-dianilino-3,6-dioxo-1,4-cyclohexadiene-1,4-dicarboxylic acid; and (iii) about 3 to about 20 parts by weight, per part of component (a)(i), of a dehydrating agent, with the proviso that if either component (a)(i) or component (a)(ii) is a 2,5-dianilino-6,13-dihydroterephthalic acid or derivative thereof, reaction step (a) additionally comprises an oxidation step; (b) drowning the reaction mixture from step (a) with a liquid in which the quinacridone pigment is substantially insoluble; and (c) isolating the quinacridone pigment.
